Combine Parmesan, oregano and thyme in heavy plastic or paper bag. Add bread cubes; toss to coat evenly with cheese mixture. Spread bread cubes in even layer on ungreased jelly roll pan. Bake at 300 degrees for 35 to 40 minutes or until lightly browned and crisp, stirring occasionally. Cool, then place in freezer storage bag; freeze until needed. Makes about 2 cups.
